MOLD.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed August 17, 1909. Serial No. 513,319.

To all whom 'it may concern:

Be it known that I, .PETER M. MCNABB, a

` citizen of the United States, and a resident of Joliet, in the countyof Vill and State of Illinois, have invented certain new and usefulAImprovements in Molds, of which the following is a specification.

This invention relates to improvements in molds for forming lay-figuressuch as are `commonly usedby dressmakers, tailors, and

others, for tting and draping gowns, dresses, and other garments.

The object of the invention is to provide a `mold for this purpose,whereby a figure may be produced which will conform to the ligure of themodel, reproducing not only measurements but any lack of symmetry orpeculiarities of posture.

. To this end my improved mold comprises the various features` anddetails of construction hereinafter described and claimed.

In the accompanying drawing, in which my "invention is fullyillustrated-Figure 1 isa perspective view of a lay-figure showing a.mold of my invention applied thereto as it will, in practice, be appliedto living models. Fig. 2 is a rear View of the back section of the saidmold when removed. Fig. 3 is a fragmentary detail sectional view takensubstantially on the line 3 3 of Fig. 1, showing the covering forthe'body of the mold and the means for connecting the different sectionsthereof; and Fig. 4 is an enlarged view of one of the strips of the moldshown in Fig. 3.

- Referring now to the drawings, A designates a lay-figure, which isillustrative of a substantially half length view of a living model ofwhich a facsimile lay-gure is to be produced, and B designates, as awhole, a

plied to the lay-gure A, as in'practice it will be applied to a livingmodel.

The frame of the mold B is made of material of such` character that itwill be soft and plastic when heated, and will be set and rigid whencold. In practice I have used for this purpose what is commonly known tothe trade and in` the art as modeling compound, commonly used bydentists for taking impressions of the mouths of patients. My invention,however, contemplates equally the` use of any other material possessingthe characteristics specified. In the preferable vform thereof shown inthe drawings, the

frame of the mold B is a skeleton structure consisting of strips ofmaterial l which extend lengthwise of the mold and, `so far as possible,are preferably continuous from top to bottom thereof, and transversestrips 2 which connect said strips l, thus forming spaces or openings 3between said strips.

My invention, however, contemplates equally `4 constructing said moldsfrom continuous `sheets of material, if desired. lVhichever constructionis used, however, care must be exercised to provide a sufficient body ofthe' compound so that .it will retain its heat and plasticity for asutlicient length of time to permit it to be applied and conformed tothe model, inthe manner presently described.) In practice, I have used,with highly satis'- factory results, strips of compound 1 and 2 about of`an inch wide by i ofan inch thick, the edges thereof being preferablyrounded to i'ender them less cumbersome and bulky. The frame of themoldB comprises a plurality of different sections consisting, as shown, of afront section B1 and a baci section B2, said sections being providedwith suitable cut-out portions or openings for forming arm holes, neckopenings, etc. To provide for removing the `mold `from the model, thesections B1 and B2 are detachably connected at their meeting edges, asby glove fasteners 4. To provide for taking up any fullness due tofitting or conforming the mold B to the model, one or both of thesections B1 B2, as shown, the back section B?, is divided from top tobottom to form separate parts or pieces 6 and 7 so proportioned that,within their designed limits of use, the edges of said parts or pieces 6and 7 will overlap, as shown at 8. The overlapping edges of said partsor pieces 6 and 7 are adapted to be connected in fixed adjustment afterthe mold has been fitted to the model in any desired or approved manner,as by strips on one thereof adapted `to engage corresponding buckles onthe other, Over the shoulders, the edges of said sections B1 B2 are alsoadapted to overlap, the overlapping edges thereof being connected infixed adjustment as by straps and buckles, or in other desired manner.

The material or compound for forming the frame of the mold is preferablyincased in a close fitting covering 9 of suitable liable `material,preferably li ht, stronntl ablvent the compound,vwhen being applied'tothe model and while in a heated condition, from coming into Contact withand sticking to the clothing or person of the model in case saidmaterial issticky when heated. To

effect a close union betweensaid covering' and the material forming theframe of the mold, said covering, in addition to being stitched in themanner described, will preferably be applied so as to adhere closely tothel frame ofthemold. I/Vhere the material ofwhichthe frame of the moldis made is sticky when heated to a degree of desired plasticity, as isthe case with modeling comf pound, this may be conveniently effected byapplying said covering to the frame of the mold when heated. When thematerial which forms the frame of the mold is not sticky when heated, itmay be applied by means of av suitable adhesive.

While, due to the overlapping of the parts or Ypieces 6 and 7 which formthe back sections of the mold, any given mold is adapted for use informing figures of persons varying considerably in size, a series ofmolds of different sizes will preferably be provided, to accommodate allsizes of people. c

While I have shown my improved mold as made in two sections, this ismerely illus trative, `and my invention contemplates forming said moldin any desired number of sections.

The preferable method of forming my ,improved mold is as follows Theparts or pieces 6 and 7 of the back section B2 of the mold are firstconnected to opposite edges of the front mold section B1, which can beconveniently done by means of the glove fasteners 4. The mold is thenheated, a desir- -1 able temperature where modeling compound is used formaking the mold, being about 165 degrees. When the compound is heatedthroughout, the mold, now plastic, is applied to the model. Vorlingrapidly on ac of the parts 6 and 7 forming the back sections B? of themold are connected, as by the straps and buckles provided. The mold isthen permitted to remain on the model until it becomes thoroughly setand rigid, where-V upon the front and back sections B1 andv B2 Y aredetached from each other and removed from the model. In vcase it isdesired to .cast

vthe lay-figure at a single operation, the secprises a coveringconsisting yof continuous I sheets or layers of suit-able stiff materialwhich, in molding said lay figure, is first applied to said mold in theform of a lining, preferably in sections corresponding Vand confonningto the sections B1, B2 of the A mold. Said sheets or layers thus appliedwill prevent the plastic material from which thebody of the lay figureis formed, from bulging or protruding through the openings in the mold,which would render the surface of said lay figure uneven or humpy. c

A particular advantage which my improved mold possesses is that; it maybe used over and over again almost indefinitely in forming lay figuresof different persons or,

models, Whereas, all other molds for this purpose of which I have anyknowledge, admit of being used for a single person or model only.

I claim 1. A mold the frame of which is made of i material which isplastic when heated and is setand rigid when cold, whereby when heatedsaid mold may be conformed to the model and when cold will retain itsshape during the molding of thegure, said frame comlprising sectionsconstructed and arranged to e detachably connected to each other,substantially as described.
